How do we do it? 1.) Forwarding ICS Files to External Recipients

  • Artigo

Consider the following scenario:

 

You create a Meeting Request, add an External Contact from your Outlook Contacts for Ex: External@Something.com

 

 

You want to forward this as iCalendar to somebody for Ex: Somebody@Something.com

 

A new Email is created with the .ICS File as attachment:

 

If you save the .ICS File to your desktop for Example, and open it with Notepad, it should look like this:

The important thing we want to underline here is the ATTENDEE Line, this must have a valid Email Address per RFC: https://www.ietf.org/rfc/rfc2445.txt in the form of john_doe@host.com . If we don’t have this, this won’t work as expected.

 

 If you have any questions, please send me an Email to patrisel@microsoft.com
